This slow cooker sausage casserole recipe is the last one (for now!) that I fancied making after searching the Olive magazine website for slow cooker recipes.   As we head into autumn and colder weather, there's nothing better than comforting food...and a sausage casserole is just that!  

The end result is super tender sausages and the beans with bacon, leeks and peppers is delicious and full of flavour.

Tips

  • Stock - start off using 100ml of stock and if you find there's not much liquid when adding the peppers and beans, add in the other 50ml.
  • Beans - if you can't get borlotti beans, haricot, pinto and cannellini beans are good substitutes.
  • Enjoy with some crusty bread or on a baked potato - yum!
  • This slow cooker sausage casserole recipe is easily adapted if you’re cooking for less or more people, if you have a bigger slow cooker.

How to make this Slow Cooker Sausage Casserole

Ingredients

  • 1 tbsp olive oil for frying
  • 8 to 10 pork sausages
  • 6 rashers smoked streaky bacon (or 3 rashers smoked back bacon), chopped
  • 1 large leek, sliced
  • 1 clove garlic, sliced
  • 100 to 150ml chicken stock (see Tips)
  • 1 glass white wine (approx. 125ml)
  • a pinch of chilli flakes
  • 2 tbsp tomato purée
  • 3 roasted red peppers from a jar, chopped
  • 400g tin borlotti beans, drained and rinsed (see Tips)
  • salt and freshly ground black pepper
  • a small bunch of flat leaf parsley, roughly chopped

To serve (optional):

  • crusty bread

Instructions

  1. Heat the slow cooker to high. Heat the olive oil in a large frying pan over a medium to high heat and brown the sausages all over, making sure you get a really good colour on them (around 8 minutes). Remove from the pan and set aside, then cook the bacon until crisp and golden (around 5 minutes). Add the sausages and bacon to the slow cooker along with the leeks, garlic, stock, wine, chilli flakes and tomato purée. Cook for 2 hours then add the peppers and beans and cook for another hour. Season and stir in the parsley before serving.
